To connect the STM-1/OC-3 PSTN interface:
1. Remove the protective dust plug from the device's SFP transceiver module.
2. Connect a twin, single-mode fiber optic cable with LC-type plugs to the STM-1/OC-3
PSTN SFP transceivers (labeled
PSTN - A ).
3. For redundancy, connect a twin, single-mode fiber optic cable with LC-type plugs to
the second pair of STM-1/OC-3 SFP transceivers (labeled
PSTN - B ).
Figure 3-2: Cabling the PSTN Fiber Optic Interface
Notes:
•
To ensure full 1+1 redundancy protection, two pairs of fiber optic cables
must be connected to corresponding PSTN connectors on RTM-6310
(i.e., PSTN ports
A and B ).
•
RTM-6310 provides both T3 and STM-1/OC-3 interface ports. However,
only one interface type can be supported per deployment (software
configurable using the PSTNTransmissionType
ini file parameter).
3.3.2.2 Connecting T3 PSTN Interfaces
RTM-6310 provides three pairs of Molex mini-SMB receptacles for providing up to three T3
PSTN interfaces. Each mini-SMB pair provides a female connector for receiving and a
female connector for transmitting. These SMB jacks must be connected to coaxial cables
(not supplied).
To interface with the SMB receptacles, you need to provide (i.e., not supplied) the following
items:
„ Cable: RG-179/U coaxial cable (refer to figure below).
„ Connector: 75-Ohm male mini-SMB terminated on a coaxial cable (refer to figure
below).
